Do pets / animals go to Heaven?

Creation is base on trinities, men have a body sould and spirit and so do animals, however, men become living souls. Nothing in Scripture indicates that animals become living souls. At death men's spirit returns to God and animal's spirits return to the earth. Men's souls depart at death unto their eternal abode, heaven or hell, animal's souls would be as if they never were, the same as a child that died before birth never having become a living soul.

Ecclesiastes 3:19-21 For that which befalleth the sons of men befalleth beasts; even one thing befalleth them: as the one dieth, so dieth the other; yea, they have all one breath; so that a man hath no preeminence above a beast: for all is vanity. 20All go unto one place; all are of the dust, and all turn to dust again. 21Who knoweth the spirit of man that goeth upward, and the spirit of the beast that goeth downward to the earth?

Ecclesiastes 12:7 Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.

Job 3:16 Or as an hidden untimely birth I had not been; as infants which never saw light.
